Hello
I need to generate a current square wave, with voltage and current that can vary,
the DC / DC Boost Converter circuit allows me this.
But I doubt if you have any limiting the output frequency signal can i manipulate.?
The product I saw on amazon
DROK® 12A 600W DC Boost Converter 12-60V to 12-80V Voltage Step-up Power Supply
I need to generate a square signal to be applied to a resistive load with an output voltage range aprox of 20V to 100V, maximum current of 4 A.
But my question is whether the frequency at which this switching square wave have a limiting for normal operation of the circuit?
Hello Rodrigo,
Is the ASIN of the product you are referring to B00E8D7XYG?
If yes, the product (ASIN: B00E8D7XYG) is DC to DC Boost Converter. The electric wave of DC is nearly like a straight line. Basically, there is no square wave.
Besides, the output voltage range is DC 12-80V. If you need the output voltage of 100V, this product maybe not suitable for you.
Hope this will be helpful to you.
Best regards
Hello
I understand, but I’ll control a relay to generate pulses to generate the square wave, the booster converter have options to varying its voltage and current so it is useful for my porpouse, i use it as a power source for a resistive load. The question is whether this switching (eg go from 0V to 40V) at a certain frequency may be a limiting factor for the boost converter circuit?
Hello Rodrigo，
Thank you for writing in.
Could you please tell us the frequency of the square wave?
And is the square wave connected to the input of the product?
Waiting for your reply.
Thanks
Hello,
Frequencies between 100 Hz to 1000 Hz.
The output signal is connected by a relay to the load.
The square signal is generated with the output of the circuit
Hello Rodrigo,
Thank you for your patience and cooperation.
As your description, the relay is connected to the output of the product.
Therefore, the frequency at which this switching square wave do not affect the normal operation of the circuit.
Hope this can help you.
Best regards
Rodrigo Cavajal
